Glycolysis is the process by
which energy is harvested from glucose by living things. Several of
the reactions of glycolysis are thermodynamically unfavorable
(nonspontaneous), but proceed when they are coupled with other
reactions.
Which of these reactions is (are) unfavorable? Select all that apply. Which of these reactions can be coupled so that overall reaction is favorable? Select all that apply. What is the net change in free energy if one selection from part (b) is coupled so that the overall reaction is favorable?
